摘要
输卵管银夹绝育术后6～8年,要求取夹输卵管吻合术5例。对夹下、夹旁输卵管组织作了光镜观察并对银夹和夹下、夹旁输卵管组织进行了电子探针分析。光镜下发现夹下、夹旁输卵管肌层及外周结缔组织中,可见多量细小、疏散的黑色颗粒沉着,经电子探针分析证实为银颗粒。电子探针分析银夹被硫腐蚀,其硫含量约为新银夹硫含量的320倍。腐蚀银夹比新银夹中银含量减少约13%。结果提示:银夹在机体内长期存放其银颗粒可沉积在局部组织。
The tissue changes in fallopian tubes in 5 cases after sterilization with silver clips for 6～ 8 years were examined under optical microscope,and the composition of the silver clips were studied af- ter removal during salpingosalpingostomy.By observing under optical microscope,a lot of small,scat- tered,black particles were found deposited in muscularis and connective tissue of the tubes,locating be- low and around the clips.The deposit particles were proved to be silver with electronic probe.The sil- ver clips were deteriorated with sulphur,as tested by electronic probe.The sulphur content in the dete- riorated clip was about 320 times as much as that in the new clip.The silver content in the deteriorated clip was about 13 percent lower than that in the new clip.The result suggested that silver in the silver clip laid in the body for a long time could deposit into the surrounding tissue.
